Definitions

  • the invention relates to a method for trimming vegetables, in particular branch and leaf vegetables such as lettuce, chicory, batavias, celery branches, cabbage, fennel, etc., as well as the devices and installations for implementing this method. .
  • the dressing of vegetables such as salads is the operation which consists in preparing the vegetable for its consumption, in particular in separating the non-consumable and / or unsightly parts.
  • the present invention proposes to provide a mechanical process for trimming vegetables which allows automation of this operation in a transfer chain, in order to ensure rapid, economical and efficient processing of vegetables, this process also allowing a wide variety of 'uses depending on the type and / or size of the vegetable, thanks to the versatility of the tool used to implement the process.
  • the method according to the invention is characterized by the fact that the vegetable is mechanically held and a cutting tool deformed during its rotation is pivoted and slid axially with respect to the vegetable.
  • This process makes it possible to carry out mechanically, in a precise and safe manner, the separation of the peripheral leaves from the vegetable as well as, in the case of choking, the separation of the hard portion of connection to the root, thanks to the controlled deformation of swivel cutting tool.
  • This controlled deformation also makes it possible to easily adapt, possibly automatically, the tool to different vegetables and / or of different types.
  • the deformation command of the deformable tool can be of different types.
  • the tool is deformed by centrifugal force. It is the speed of rotation of the tool which then determines its shape in operation.
  • the deformation of the tool can also be carried out by additional mechanical means controlled electrically, pneumatically, hydraulically, etc.
  • control of the shape of the tool can be carried out by various means, for example mechanically, or by optical color reading.
  • the vegetable having undergone the preceding stripping operation has a spherical, cylindrical, conical or, preferably of the so-called "patatoid” type, that is to say with a curvilinear generatrix.
  • a following operation can be provided, characterized in that the stripped vegetable is given a cylindrical shape and it is advanced against a coaxial rotary cutting crown.
  • the invention provides that the vegetable leaving said crown be brought opposite at least one rotary knife with axis of rotation orthogonal to the axis of said crown.
  • the invention provides that one uses, in a manner known per se, a pivoting tool of the fixed router type, instead of a deformable tool.
  • the invention also relates to a device and an installation for implementing the method according to the invention.
  • the installation represented in FIGS. 1 and 2 comprises a loading mat 1 of a reception bank 2 from which the vegetables to be trimmed are manually introduced into a processing carousel 3 which, in the example described, is mounted vertically for reasons of space saving.
  • Carousel 3 which constitutes a transfer machine, can be horizontal or inclined. It can also be replaced by a non-circular transfer machine, for example rectilinear.
  • the vegetable to be processed 4 for example a salad, is entered in a gripping head 5 shown in more detail in FIG. 3, which successively brings it to various work stations 6.
  • An adjustable stop 7 serves for positioning the vegetable 4 .
  • the vegetable passes through a slicing station 8 which will be described in more detail in relation to FIG. 4, then through a stripping station 9 which will be explained with reference to FIG. 5.
  • the vegetable arrives at a pick-up station 10 external foliage where, pushed by a jack 11, it will undergo a peripheral cut, as will be seen in more detail with reference to FIG. 8.
  • the vegetable 4 is separated in two by a cutting disc 11 and driven by a carpet of inspection 12 to a packaging station (not shown).
  • the lower part of the carousel 3 is closed by a casing 13 which makes it possible to collect the waste which is evacuated by a mat 14.
  • the gripping head 5, represented in FIG. 3, comprises a fixed support 14 provided with a semicircular opening 15 and with respect to which a jaw 16 slidable by a spring 17 can slide.
  • the jaw 16 comprises a semicircular opening 18 so that, in the closed position (lower part of the figure), the two openings 15 and 18 form a tightening circle for a vegetable and, in the open position (upper part of the figure), the two openings 15 and 18 are pushed aside to release the vegetable.
  • the vegetable 4, held by the gripping head 5, is subjected to a stripping by a tool 20 mounted pivotally and sliding axially relative to the vegetable 4.
  • the tool 20 can be, as shown in FIG. 1 , a classic spinning top. Preferably, it consists of a variable tool which will be described in more detail with reference to FIG. 5.
  • the vegetable 4 held by the gripping head 5 is subjected to a peripheral stripping operation by means of a deformable tool 21 according to the invention.
  • the tool 21 is formed by a flexible bell-shaped blade rotatably mounted on a shaft 22 carried by a sliding support block 23 which carries the drive motor of the tool 21 and can move axially with respect to the gripping head 5.
  • the flexible blade 21 deforms radially as a function of the speed of rotation of the shaft 22, by the effect of centrifugal force resulting from its own weight and balancing weights 24 fixed in the vicinity of its free edge.
  • the blade 21 can be given a more or less flared bell shape which will determine, during the advance of the tool 21, the peripheral portion detached from the vegetable 4 during the advance of the support block 23 from right to left (in the drawing).
  • a rigid blade articulated on the shaft 22 and deviating more or less from the axis of this shaft as a function of the speed of rotation.
  • the blade can be articulated at one or more intermediate points.
  • the shape of the blade 21 can be rectilinear, in an arc, and have a parallel or oblique movement relative to the axis of the shaft 22 by means of sliding guides (not shown ). It is thus possible to obtain very varied forms of the leafless vegetable such as frustoconical, spherical, etc.
  • the tool 21 can be deformed other than by the use of centrifugal force, in particular by the use of mechanical means for deforming the blade or moving the blade.
  • These mechanical means can be actuated electrically, hydraulically, mechanically, or by any suitable mode.
  • the deformation and / or movement of the deformable tool can be controlled manually, mechanically, or automatically.
  • an automatic control one can use for example a color reader detecting for example the appearance of the yellow of a salad. This saves the material as much as possible.
  • the vegetable 4 which has undergone stripping which has just been described can then be subjected to an operation for removing the outer foliage which has not been separated by the preceding stripping operation. This is illustrated in Figure 6.
  • the vegetable 4 is pushed in a substantially cylindrical form of revolution through the circular opening of the gripping head 5. This movement is carried out by a vegetable pusher 25 actuated by a buffer cylinder 26 (shown in Figure 2).
  • a rotary circular crown 27 is disposed at the outlet of the gripping head 5 coaxially with the axis of the circular opening of this head 5.
  • the crown 27 is provided, opposite the gripping head 5, with an edge cutting 28, for example provided with teeth, so that the vegetable 4, pushed by the vegetable pusher 25, crosses the crown 27 whose cutting edge separates the foliage which is outside the crown.
  • a rotary knife 11 can be placed at the outlet of the crown 27, for example, in a plane passing through the axis of the crown, so as to cut the completely stripped vegetable 4 in half.
  • the pieces of vegetable can then fall onto the inspection mat 12 where it is examined and sorted visually or, possibly, automatically.
